Matheny did one of my biggest pet peeves last night man. Walking a guy to make the bases loaded with an average pitcher who sometimes struggles to throw strikes. Puts way too much pressure on the pitcher. And Salas is that, and he walked the guy on 4 pitches.
Unless it was 2nd and 3rd with 1 out and you're trying to set up the double play, I never really understood intentionally walking the bases loaded. There probably are exceptions though.
